SPECIFICATION forming part of Letters Patent No. 587,288, dated July 27,.1897.

Application filed October 1894. Serial No. 525,448. (No model.)

To ctZZ whom, it may concern: I

Be it known that I, ARTHUR R. BAILEY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in TypeJVriters; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention has reference to typewriters;

' and the object of the invention is to provide anism does rest.

To this end the invention consists in the construction of a machine withpower connections responsive to and connected with the key-levers andserving to complete the action initiatedby the movementof a key-.

lever and to actuate the type-bar and make an impression, allsubstantiallyas shown and described, and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of myimproved machine, having a portion broken out and showing the operatingparts in a position of rest and ready to operate. Fig. 2 is a horizontalplan View on a line corresponding to 2 2, Fig. 1, and

looking down on the operating-roll and the auxiliary levers shown inelevation in Fig. 1.

Fig. 3 is a sectional and detail view of a single type-bar and itsconnections, said bar being down, as occurs when the operating parts areactuated, as in Fig. 2. Fig. 4 is a crosssection of a pair of levers andan edge view of their keeper and its connection, as hereinafter fullydescribed.

The invention herein shown and described is not designed to be used withsome particular make of machine and none other, but is adaptable to anyof the standard machines with a comparatively slight modification ofparts to make room for the introduction of the extra mechanism.

In the accompanying drawings Ihave shown a suitable frame A with whatmay be termed the usual keyboard and keys B and the main or key levers 0running to the rear of the machine and pivoted on a common pivoted rod2. These key-levers C are understood to be constructed after the mannerof the usual key-lever in material and form and have in addition to theusual construction a rightangled arm or bell-crank arm 3 at their ends,and to the upper ends of these arms are attached the auxiliary or powerleversD. These power-levers'are partially supported at their front endsby rods or Wires 5, connected to the short ends of the finger-pieces ortypearms 6, behind the pivot-points 7 thereof. These wires or rods 5,through which the typearm is actuated and thrown into working position,are the usual-rods or wires which in the ordinary machine are connecteddirectly with the key-lever O. Inv this case the said wires 5 areattached to the upper ends of the metal straps or keepers 8. (Shown inedge vieWinFig/L) Thesestrapsarebentasshown in Fig. 4., so as toin'close the key-lever O and keep it within certain limits and free tomove up and down independently of the strap, and the ends of the strapare fixed to the auxiliary or power lever D. This is the same in efiectasattaching the rods 5 directly to the powerlevers.

It will be seen in Figs. 1 and 2 that the said straps or keepers 8 arearranged alternately at the front and rear of the transverse guideframefor both said sets of levers and consist in this instance of threehorizontal bars 9, 10, and 11, through which pass the guiderods 12, thatserve as guides or stays for the said levers and confine them laterally,so that they will only have an up-and-down movement. Any other suitablemeans than the cross-bars and separating-wires 12 here shown may besubstituted for these parts, if desired.

A suitable retractin g-sprin g 14 is connected with each auxiliary leverD at its rear in troduce a cylinder E transversely of the machineimmediately at the rear of the keyboard and in close proximity of theends or extremities of the power-levers D. This'cylinder or tube E issupportedin any suitable bearin gs at its ends, and it may be made ofany suitable material, the purpose thereof being to make frictionalactuating engagement with the extremity of the power-lever D momentarilyand instantaneously with the depression of the corresponding lever G.Then contact be,- tween said power-lever and cylinder is made, thepower-leverD is down at its front end, and this operation throws thecorresponding typebar 6 into printing position. Hence the free end oflever D and the surface of the tube or cylinder E may one or both befaced with rubher or other material, or be of such material themselvesas to make certain frictional contact and avoid slipping.

In operation, to effect contact between a power-lever and the' cylinderit is only necessary to depress the key B sufficiently to carry thelever D forward into touch with the cylinder E. Obviously this action ofthe operator will be a very easy one for the reason that the levers Cthemselves are long and havea very short arm 3 to operate the swingingpowerlever D. The space between the extremity 16 of lever D and thecylinder E is very slight, it only being necessary that there should beseparation at this point and nothing more. Hence a very slight movementcomparatively and a very easy one of any one of the keylevers will throwits power 'lever D into con tact with the said cylinder, and since thesaid cylinder is supposed to be rotating at a suffieient rate of speedto give an instantaneous action to the type-bar when touchloy lever Dhas been effected it will be seen that the operator will no sooner havecaused a depression of a key than that the corresponding character willrespond and make its impression. To operate said cylinder of tube E, Ihave shown here a cord 18, which passes over a sheave 19 upon the end ofthe cylinder, which cord is connected with any suitable driving power.This power may be a permanent power-shaft or it may be a motor of somekind, or even be a treadle. In fact it is not material what the power isif it be sufficient to drive the said cylinder at a suitable and uniformrate of speed, say one hundred (100) revolutions a minute. The instantthat a sufficient depression of a key has occurred to make contact withthe cylinder by any one of the power-levers it follows that in the sameinstant the said cylinder actuates the lever D and draws it downsufficiently to throw the printing-characters into printing position.The two operations of depressin a key and making an impression aresimultaneous and instantaneous. This not only effects a very greatsaving of labor and strength to the operator, but it greatly facilitatesthe work, because, in the first place, the actual work is done by thepower mechanism and only an initial or startin g touch is required uponthe key. In the next place the distance to which the key is depressed inthis improved operation is considerably less than in the old style ofmachine, and hence the act of depressing the key requires less time andfacilitates speed of operation. Obviously as soon as the operatorwithdraws his touch from the key the spring 14: at the rear of thelevers asserts itself and draws the power-lever D out of contact withthe cylinder. The parts are then not only released at that point, butthe power-lever D is instantly restored to its normal position, where itawaits further use, and in the same instant the actuated type-bar dropsback out of use and out of the way.

All of the keys and type bars or arms are similarly connected, so that adescription of the operation of a single keyand its connected andcoacting parts serves-for all.

Sometimes it may occur that the operatorwill want to run the machinewithout the power connections. In that eventhe simply has to throw thepower-cylinder E out of possible engagement with the ends 16 of thelevers D and depress all the levers C in their keepers S to the bottomthereof, so that when the operator touches any one of the keys it willact directly upon its type-bar through the lever O, keeper S, andoperating-rod 5. Thus, for example,referring to both Figs. 1 and 4, itwill be seen that in the said keeper the lever O normally is slightlyabove the bottom of the loop thereof. Now assuming that the power is notto be used the operator simply throws the arms 20 of the pivotedcylinder-bearing pieces 21 toward the rear of the machine and therebydepresses all the levers 0 through the cross-rod 22, connected to thelower ends of the said bearing-pieces 21. These pieces are pivoted onthe main frame 'at 23, and they have suitable bearings for the cylinderE, as hereinbefore described, as well as the other features ofconstruction shown, to move the cylinder from one position to anotherand to depress the key-levers. IVhen this occurs, all the levers C willbe down to the bottom of the loop in the keepers 8, and then thecylinder E will not only be withdrawn from the ends of the levers D toprevent possible contact, but the depression of a key B will at once actdirectly upon its type-arm. Springs 24 at the sides of the machine serveto keep the cylinder E normally raised to acting position.

Obviously the construction for hanging and operating the cylinder E andfor depressing the levers O might be very considerably changed from whatis shown here and still serve the same purpose. I do not, therefore,deem my invention as being limited by the construction of parts as hereshown and edscribed so far as this cylinder is concerned. Indeed, theremay be modifications and changes in all parts of the machine in whichthe invention occurs without departing from the spirit thereof.

The power-cylinder might be fluted or coractuated lever secured thereto,a transverse ru-gated longitudinally and. the ends of the power-leversconstructed to engage therewith, so that there would be positive powerengagement at this point instead of frictional engagement.

Having thus described my invention, what I claim is 1. In type-writers,a key-lever having a rigid annular extension near its pivot-point, apower-lever connected to said extension, a type-bar and a, support forthe free end of the power-lever connected with the said type-bar, and apower-communicating medium for the power-lever arranged to contact withthe same at its front end, substantially as set forth.
